App crashes (PocketSphinx) as soon as I SIMPLY add qtMultimedia to project

Hello there.
I am using PocketSphinx source code to simply use its 'speechToText' funcionality as described inhttp://snipt.org/GRkl0
It works perfectly but as soon as I add (in my .pro file) qtMultimedia, application crashes.
The crashing line is

as soon as I remove the last two lines (after a "clean all") it works like a charm again...

? Everything is installed properly, at least qtmultimedia funcionalities works fine in other project on the same machine.
No other code is used than the one shown in the link (you can easily replicate this crash).

I would guess that qt multimedia and your pocketsphinx are using conflicting (versions of) libraries. Stuff like this is annoying to debug:)

To get started you can check the output of ldd of the qt multimedia and pocketspinx libraries.

If this is indeed a issue of conflicting symbols, then you will need to rebuild one of your libraries to use the same dependency as the other or put (one or both) of the dependent libraries into a namespace.
